In order to stop the condensation/ You need insulation. Condensation comes from warmer moist air contacting a colder surface.

If the LineX or Rhino Liner provides the insualtion. Then yes it will work. Check and see what the "R" value of Line X is for a typical application.  The typical 1/4" thick LineX I've seen probably doesn't offer substantial R value.

I'm having the same dilema with my tack compartment and it's caused rust.  I'm having my trailer sandblasted and repainted and also having the same done inside the tack area. 

Lookin for ideas on how to prevent the moisture causing the rust.  Even wondered if I put some kind of vent in if that'd help.

What thread should I inquire on to see what suggestions you had about insulating the tack area?  Thanks!

I found this information on the "It's Cold!" thread, from houndog...

I used R/MAX insulation bought at Home Depot or Lowes on our steel trailer with 6 foot short wall dressing room.It had vinal on one side and what looked like alumn foil on the other.Its used on homes before vinal siding is installed.I glued it on with a Tough As Nails product in a caulk gun.On front of nose it can be scored and snapped to fit around the curve.I glued the vinal side down.Then bought a on sale carpet with RUBBER backing and used a spay glue so it could be moved around for good fit.Did walls,roof,gooseneck floor area etc.with a straight edge,razor knife,ruler it took wife and I two complete weekends to do.In 30 degree weather or less in the morning could take a small propane heater sitting on a upside down water bucket and have it in high 50s to mid 60s in 10 minutes or so.A cheap mattress,good covers,warm it up good and then turn in.Manage to stay snug until morning and then warm it up again.Its been installed since 1995 and other a couple of minor puckered areas that had to be reglued.

Thanks for the information! 

I've called the manufacturer of the trailer and they've asked me to send them pictures and then they can give me some ideas so hopefully they'll have some good ones.

Look at where the moisture is coming from and see if you can reduce or elminate the moisture.

Do you have condensation only when you sleep in the trailer.  Only when you run your heater, or do you have condesation ALL the time.

If you live in a very humid climate, you have a much harder battle. As outside here you let in for ventelation renews the humidity. And thereis very little you cando to remove the humidity from the trailer. So you are just left with minimizing the condensation.

Propane heaters in particular release moisture into the air as they burn. So if you are using a propane heater, you want to make sure the exhaust gases are vented outside the trailer. Most built in forced air heaters do this. But your carry around heaters, Like a Heater Buddy or Catalytic heater don't exhaust those gases.

Built in forced air heaters will help. As they dry the air as they heat it. Thats why we install so many Humidiifiers on Furnaces in my area of the country. We have so little humidity to strart with, that after running the furnace, there is no moisture in the air and your skin dries out and gets itchy.
